If the sales representative is able to get 20% of the prospective customers to subscribe, the maximum expected number of subscriptions per week is 34. If the sales representative earns $3 per subscription in addition to daily wages, the minimum expected value of the extra income per week is $94.20.
For the first answer, refer to the attached solution. Add the data each week, then multiply the sum by 20% to find out which has the maximum expected number of subscriptions.
For the second answer, the minimum expected value in week 2 multiplied by $3 to get the minimum expected value of the extra income in that week.
